SEWER-TRAP.

SPECIFICATION forming part of Letters Patent No. 250,511, dated December6, 1881.

Application filed June 24, 1881. (No model.)

To all whom it may concern Be it known that I, GEORGE EIoHER'r, ofCincinnati, Hamilton county, Ohio, have inventedanew andusefullmprovementin Sewer- Traps, of which the following is aspecification.

The object of my invention is a combined outlet and sewer-trap which iseasily kept free, is gas-tight, and is accessible for inspection orrepair from the interior of the basin.

In the accompanying drawings, Figure l is a vertical section of aportion ofa sewer catchbasin provided with my improvements. Fig." 2represents the component members of my trap detached; Fig. 3, thelifting-rod with the prongs.

A may represent any suitable sewer catchbasin having one or more inlets,B. A sink, C, in the basin-floor receives and supports by its flangedrim 1) the enlarged head or upper portion, E, of discharge-pipe F. Apot, G, whose hooked hangers H rest in recesses of rim D, receives thelower end of the nozzle I, which constitutes the basin-outlet, whosecollar J, constituting a part of thecatch-basin floor, also rests withinthe rim D, as shown. Standards K, which rise vertically from theinlet-mouth, guide and hold against lateral displacement a curb, L, thatconsists of a hollow cylinder open at bottom, and whose upper endterminates in a cage, M, having an orifice, m, to receive the lowerextremity, n, ofa rod, N, by which the said curb is made capable ofbeing lifted when desired. The engagement of rod N in orifice m is suchas to permit the rod to be rotated upon its own axis.

Projectinglaterally outward and then downward from the rod N are twoprongs, O, which follow the general contour of the curb, so as nearly totouch the same.

The pot G and outlet-nozzle I form collectivelya stink-trap, that,whilepermitting the descent of the liquid contents of the basin, effectuallyseals the sewer against the escape of its mephitic gases and vapors. Thecurb L, in its lowerornormalposition,(representedinFig.1,) prevents forthe time being the escape of solid debris, while its open cage-likeupper portion permits the liquid and semi-liquid excreta or sewage toflow off and escape. Should the interstices of said cage become cloggedwith trash, they may be rendered clear of such by rotating the prongedrod N 0 about its own axis. Finally, when it becomes desired to cleansethe basin after the removal of its more solid contents through thebasin-mouth, water is let into the basin, and the curb L M beingsuddenlyelevated, the entire contents are permitted to escape.

The parts above described are so arranged and constructed as to be alleasily accessible and capable of inspection, repair, and replacement,without going outside of the basin.

The outlet F may be led 06, either downward,'as shown, or laterally, tosuit the location in which the basin is used.

I claim as new and of my invention 1. The combination of pendent pot Gand outlet-nozzle 1, below the level of the basinfloor and within themouth of the dischargepipe, with standards K, that rise from thebasinfloor, and with the elevatable inclosing-curb L, substantially asset forth.

2. The combination, with standards K, that rise from the basin-floor inline with its discharge-nozzle, of the curb L M, whose lifting handle orrod N is pivoted in the same and is armed with prongs O, as and for thepurpose set forth.

In testimony of which invention I hereunto set my hand.

GEORGE EIOHERT.
